It might sound odd, but an old kitchen sponge can actually be surprisingly useful in the washing machine. Before tossing it out, you can give it one more job.

How It Helps
When you place a clean (but worn-out) sponge into your washing machine, it acts like a lint collector. As clothes tumble around, the sponge helps trap hair, lint, and small fibers that would otherwise stick to your clothes—especially useful if you have pets.
Great for Pet Hair
If you constantly deal with fur on clothes, this simple trick can make a noticeable difference. The sponge helps gather loose hair during the wash, reducing the amount left behind on fabrics.
Important Tips
Make sure the sponge is clean and free of food residue or grease before using it
Avoid using sponges that are breaking apart, as they can leave bits behind
Use it mainly for loads with heavy lint or hair, rather than delicate fabrics
A Smart Reuse Idea
This is an easy way to extend the life of something you’d normally throw away. It won’t replace proper lint filters, but it can give your laundry a little extra help.
Final Thought
Simple household hacks like this can save money and reduce waste. Just be sure the sponge is clean and in good condition before tossing it into your wash.
